Block Diagram
PT8A2703 i s des igned a s a m ixed sig nal dev ice to
provide a s ingle ch ip so lution for rechargeable ba ttery
powered smart con trollers using only a few ex ternal
components such as transistors, passive components and
LED. T he ch ip hand les c harging with fa st con stant or
pulse current cha rging m odes and disc harging. It
contains eno ugh log ic c ircuits on ch ip to implement
custom applications such as clipper, hair remover, high-
end toy/aeromodelling and other portable devices.
